LoriotPro has extended the LUA sripting language by providing its own LUA libraries. The new functions provided are dedicated to the creation of monitoring and SNMP automation application.


‘buffer’ =  lp.CliPlugin('uid','Command');


The lp.CliPlugin LUA function performs communication with a Directory plugin. Each plugin provide a command line interface aloowing external LUA programme to exchange data with it. Each plugin has its own set of commands with proprietary syntaxes. Some command are common to all plugins.


‘uid’                  An unsigned 64bits number (Unique Indetifier) within a character string that is the reference to a specific pluigin in the directory. When a plugin is created it is assigned a unique identifier.

‘Command’       The command to send to the plugin as a character string.

Return Values

‘buffer’                A character string containing the result of the command. The buffer provide a number in first that give information of the processing status.

It is recommended that the returned code follow the standard defined in RFC 959

551 Requested action aborted: page type unknown.
552 Requested file action aborted. Exceeded storage allocation (for current directory or dataset).
553 Requested action not taken. File name not allowed.



First of all for coding the function, you can use the Insert Directory UID object Wizard to get the UID of a plugin.




In the upper example, the command doesn't exist and the plugin return the value 500.

To discover the commands available of a plugin should provide the command :

get plugin cli help


This command should retrun the value 200 followed by a list of commands with CRLF between. By default Plugins of LoriotPro version 5 support this commande.


The sign ‘_’ in front of a word means that it is a variable. If the variable is a character string, then she is between simple quote.

Exemple : get jpeg map '_filemane' _width _height

Some plugins are able to generate image filee in ( jpeg) showing a newtork map of a load graph.

Plugin - Activeview


To get the image we can do: get jpeg map ‘_filename’ _width _height

Warning ! The character string variable must be entered between double quote and all '\' character must be repeated twice.

result=lp.CliPlugin("5117890155264344098",'get plugin cli help');
if string.find(result,"jpeg") then
result=lp.CliPlugin("5117890155264344098",'get jpeg map "c:\\testactiveview.jpg" 400 400');



The jpeg image can be then displayed with any image viewer.


Plugin - Vumeter

It is also possible to retreive the view of the VuMeter plugin with the command:

get jpeg '_filename'

result=lp.CliPlugin("5122655816616247350",'get plugin cli help');
if string.find(result,"jpeg") then
result=lp.CliPlugin("5122655816616247350",'get jpeg "c:\\testvumeter.jpg"');



 Plugin - Graphe Linéaire

It is also possible to retreive the view of the LinearGraph plugin with the command:

get jpeg '_filename'

result=lp.CliPlugin("5122678116086448188",'get plugin cli help');
if string.find(result,"jpeg") then
result=lp.CliPlugin("5122678116086448188",'get jpeg "c:\\testgraphelinear.jpg"');






Plugin - Spanning Tree

 It is also possible to retreive the view of the Spanning Tree plugin with the command:

get jpeg map '_filemane' _width _height

result=lp.CliPlugin("5159765313306230855",'get plugin cli help');
if string.find(result,"jpeg") then
result=lp.CliPlugin("5159765313306230855",'get jpeg map "c:\\testgraphelinear.jpg" 400 400');
